What treatment is being compared to the control in the experiment? what treatment is being compared to the control in the experiment? the treated umbilical cord stem cells were cultured in the presence of an inhibitor from glioblastoma cells, but the control cells were cultured without the inhibitor. the control glioblastoma cells were run through the flow cytometer and then treated by being cultured in the presence of an inhibitor. the treated glioblastoma cells were stained with a fluorescent dye, but the control cells were not stained. the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor?

The correct answer is: the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.

It has been shown that treatment with injected umbilical cord stem cells has strong therapeutic effects on glioma models. Those cells produce anti-tumour substances, with inhibitory effects.

Control group does not include the treatment in order to observe the treatment.

answer; ///(b) it is composed of four protein chains and four heme groups;

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
